The Minolta SrT101 remained in production for about a decade, being manufactured from the around 1966-1975 .  I suppose Minolta found that there was little improvement needed in the 101 series cameras.  As far as I can tell my example is considered one of the '2nd generation' 101s from the early 70s.  This is yet another solid, dependable, and all manual camera from the time when Japanese SLRs were really hammering the European camera industry.
